Introduction to Decorative Moldings for PVC Foam Boards


Decorative moldings made from PVC foam board (Polyvinyl Chloride Foam Board) are widely used in modern interior design due to their lightweight structure, durability, and ease of installation. Produced through an extrusion process, these moldings offer a smooth surface, stable performance, and excellent resistance to moisture and insects—making them an ideal alternative to traditional wood trim.


Key Features


Lightweight & Easy to Install

PVC foam moldings are significantly lighter than wood, allowing for effortless cutting, nailing, and gluing during installation.


Moisture & Termite Resistant

PVC does not absorb water and is naturally resistant to rot, mold, and insect damage, making it suitable for kitchens, bathrooms, and humid environments.


Smooth Surface for Painting or Laminating

The surface can be painted directly or laminated with decorative films to achieve wood-grain, marble, or solid-color effects.


High Durability

The foam structure provides strength while maintaining elasticity, making the moldings resistant to cracks and deformation.


Common Applications


Wall panel edge trims


Door and window casings


Ceiling and floor skirtings


Corner trims and decorative profiles


WPC/PVC panel joints and connectors


Advantages Compared to Wood Moldings


No warping or cracking


Lower maintenance cost


Consistent dimensions and finish


Fire-retardant (depending on formulation)


More cost-effective and long-lasting


Production Summary


PVC foam decorative moldings are typically produced by:


Compounding (PVC resin + additives)


Extrusion foaming process


Cooling and shaping


Cutting to size


Surface finishing (sanding, coating, lamination, or printing)
